The aox delete mail command inserts or updates a mail retention policy. Messages matching the policy will be automatically deleted after the specified time.
Each policy has a duration, and optionally a mailbox to which it applies and/or a search specification.
If it applies to a mailbox, it also applies to all children of that mailbox. If you specify a search, then the policy applies only to messages that match that search, otherwise it applies to all messages.
The simplest policy is one that deletes all mail after one week:
aox delete mail 7
A little more complex is one that matches all messages in certain mailboxes, such as this example, which deletes mail in some mailboxes after ten years:
aox delete mail 3660 /archive
It is also possible to specify a search. This deletes all mail from/to/… exemplo.com.br after 14 days:
aox delete mail 14 address exemplo.com.br
The next example has both a mailbox and a search:
aox delete mail 90 /archive/sales address exemplo.com.br
Note that deletion policies don't override each other. If you specify that all should be deleted after one year and that mail in /archives should be deleted after two, then everything will be deleted after one year. The way to override the one-year policy is to use aox retain mail like this:
aox retain mail 721 /archives
